They do not utilize a threaded terminal – this is a departure from the Classic and Decko turnbuckles. There are a few results of this turnbuckle design. The overall length of an Adjust-A-Body is less than that of a Classic turnbuckle. To further minimize the length of an Adjust-A-Body turnbuckle, the cable compression fitting is a short ferrule. The ferrule must be swaged by hydraulic tool in order to compress it sufficiently to the point where it fits inside the body. If you prefer not to buy a prefabricated Adjust-A-Body assembly, Lexco will rent you a tool kit that compatible with the machine swaged ferrules.
